Intel Corporation today announced that first-quarter revenue is expected to be below the company's previous outlook. The company now expects first-quarter revenue to be $12.8 billion, plus or minus $300 million, compared to the previous expectation of $13.7 billion, plus or minus $500 million.

The change in revenue outlook is a result of weaker than expected demand for business desktop PCs and lower than expected inventory levels across the PC supply chain. The company believes the changes to demand and inventory patterns are caused by lower than expected Windows XP* refresh in small and medium business and increasingly challenging macroeconomic and currency conditions, particularly in Europe.
